Description of study


The effect of land use types (sugarcane, grazing and forestry) on water quality were determined by a three year sampling study.

When and Where?

The study commenced in October 1992 and concluded in May 1995. 37 sites were chosen, each within the Herbert River. Figure 1 and Table 1 provide further details on site location and physical characteristics.


Surface grab samples of river water were taken at each sampling site on a monthly basis and after intense rainfall events. Samples were then filtered through 0.7 µm Whatman GF/F filters. pH and EC were determined from a subsample of unfiltered water and the remaining filtrate was frozen prior to further chemical analysis. Concentrations of orthophosphate, nitrate and ammonium were determined using an Alpkem segmented flow analyser.
